1.4.1 Character Signal Output When Option A is Selected

Option A

The VC1 bit of the output pin control command can be used to specify whether the characters of each row are output to

the VC1 channel. Each character can be specified to be output to the VC2 channel, and the VC1 channel outputs only

characters for which the VC2 channel in the rows for which the VC1 bit is set to 1. Characters for which the VC2 channel

is specified are not output to the RGB or VC1 channel.

Display example (when the VC2 channel is used for information to be recorded)

Characters output via RGB channel

(colored characters)

Characters output via VC2 channel

(specified characters of specified rows)

Characters output via VC1 channel

(specified rows)

• The VC1 channel outputs the

characters in the rows for which the

VC1 bit is set to 0, excluding the

characters for which the VC2 channel

is specified.

• Rows for which the VC1 bit is set to 1

are not output (the VC1 pin is fixed to

low level).

• Rows for which the VC1 bit is set to 0

are not output (the VC2 pin is fixed to

low level).

• The VC2 channel outputs only those

characters for which the VC2 channel

has been specified in the rows for

which the VC1 bit is set to 1.
